Particle size distribution curves of recycled aggregates from building demolition concrete crushed by jaw and impact crushers. The jaw crusher produced 60% of coarse aggregates in weight, whereas the impact crusher produced 49% coarse aggregates. The proportion of particles finer than 0.15 mm is around 7–8% weight for both crushing mechanisms.

CONCRETE MIX DESIGN USING CRUSHED SAND
From technical point of view the rich mixes may lead to high shrinkage and cracking in the structural concrete, and to evolution of high heat of hydration in mass concrete which may cause cracking. In this study, we have used grit and crushed sand for the design mix and found the characteristic compressive strength at 3,7 and 28 days respectively.
